现在公司旧域名 www.old.com 有业务需求有变更；
需要使用新 域名 www.new.com 代替，但是旧域名不能废除；
需要跳转到新域名上，而且后面的参 数保持不变。
[root@localhost named]# cd /etc/nginx/
[root@localhost nginx]# vim conf.d/default.conf #修改配置文件
server {
listen 80;
server_name www.old.com;
#charset koi8-r;
access_log /var/log/nginx/www.old.com-access.log main;
location / {
if ($host = "www.old.com") { #匹配如果域名是老域名
rewrite ^/(.*)$ http://www.new.com/$1 permanent; #则永久设置跳转新域名
}
root /usr/share/nginx/html;
index index.html index.htm;
}[root@localhost nginx]# vim /etc/named.rfc1912.zones
zone "new.com" IN {
type master;
file "new.com.zone"; #new区域数据配置文件
allow-update { none; };
};
[root@localhost nginx]# cd /var/named/
[root@localhost named]# ls
data dynamic named.ca named.empty named.localhost named.loopback old.com.zone slaves
[root@localhost named]# cp -p old.com.zone new.com.zone
#复制区域数据配置文件为kgc的数据配置文件
[root@localhost named]# systemctl restart named #重启解析服务
[root@localhost named]# systemctl restart nginx #重启nginx服务
[root@localhost named]#
所有IP 访问任何内容都显示一个固定维护页面，只有公司 IP ：192.168.52.129访问正常。
[root@localhost named]# vim /etc/nginx/conf.d/default.conf
server {
listen 80;
server_name www.old.com;
#charset koi8-r;
access_log /var/log/nginx/www.old.com-access.log main;
#设置是否合法的IP标志
set $rewrite true;
#判断是否为合法IP
if ($remote_addr = "192.168.52.128"){ #win10主机ip为192.168.52.129，此时129为不合法ip
set $rewrite false;
}
#非法IP进行判断打上标记
if ($rewrite = true){
rewrite (.+) /main.html;
}
#匹配标记进行跳转站点
location = /main.html {
root /usr/share/nginx/html;
}
location / {
root /usr/share/nginx/html;
index index.html index.htm;
}[root@localhost named]# cd /usr/share/nginx/html/ #切换到站点中 [root@localhost html]# ls 50x.html index.html [root@localhost html]# vim main.html #编辑非法IP访问网页内容 <h2>this is error page</h2> [root@localhost html]# systemctl restart nginx #重启Nginx服务 [root@localhost html]#
[root@localhost html]# vim /etc/nginx/conf.d/default.conf
#判断是否为合法IP
if ($remote_addr = "192.168.52.129"){ #将合法ip改为win10主机IP地址
set $rewrite false;
}
[root@localhost html]# systemctl restart nginx #重启服务
[root@localhost html]#
例如现在访问的是 http://bbs.accp.com，现在需要将这个域名下面的发帖都跳转到 http://www.accp.com/bbs，注意保持域名跳转后的参数不变。
[root@localhost html]# vim /etc/nginx/conf.d/default.conf #修改默认配置文件
server {
listen 80;
server_name bbs.old.com; #修改服务名称
#charset koi8-r;
access_log /var/log/nginx/www.old.com-access.log main;
location /post { #用location匹配post目录
rewrite (.+) http://www.old.com/bbs$1 permanent; #永久重定向跳转
}
location / {
root /usr/share/nginx/html;
index index.html index.htm;
}[root@localhost html]# cd /var/named/ [root@localhost named]# ls data dynamic named.ca named.empty named.localhost named.loopback new.com.zone old.com.zone slaves [root@localhost named]# vim old.com.zone #修改区域数据配置文件 $TTL 1D @ IN SOA @ rname.invalid. ( 0 ; serial 1D ; refresh 1H ; retry 1W ; expire 3H ) ; minimum NS @ A 127.0.0.1 bbs IN A 192.168.52.132 #www改为bbs [root@localhost named]# systemctl restart named #重启解析服务 [root@localhost named]# systemctl restart nginx #重启Nginx服务 [root@localhost named]#
http://www.accp.com/100-(100|200)-100.html 跳转到 http://www.accp.com 页面。
[root@localhost named]# vim /etc/nginx/conf.d/default.conf
server {
listen 80;
server_name www.old.com;
#charset koi8-r;
access_log /var/log/nginx/www.old.com-access.log main;
if ($request_uri ~ ^/100-(100|200)-(\d+).html$) {
#匹配正则开头为100-(100|200)-一次多次的整数html为结尾的
rewrite (.*) http://www.old.com permanent; #永久重定向跳转到主页
}[root@localhost named]# vim /var/named/old.com.zone #修改区域数据配置文件 $TTL 1D @ IN SOA @ rname.invalid. ( 0 ; serial 1D ; refresh 1H ; retry 1W ; expire 3H ) ; minimum NS @ A 127.0.0.1 www IN A 192.168.52.132 [root@localhost named]# systemctl restart named #重启解析服务 [root@localhost named]# systemctl restart nginx #重启解析服务 [root@localhost named]#
[root@localhost named]# vim /etc/nginx/conf.d/default.conf #修改默认配置文件
server {

server_name www.old.com;
#charset koi8-r;
access_log /var/log/nginx/www.old.com-access.log main;
location ~* /upload/.*\.php$ { #匹配不分大小写，匹配upload后零次或多次以.php为结尾的
rewrite (.+) http://www.old.com permanent; #跳转到首页
}
[root@localhost named]# systemctl restart nginx #重启Nginx服务
[root@localhost named]#
[root@localhost named]# vim /etc/nginx/conf.d/default.conf #修改Nginx默认配置文件
server {
listen 80;
server_name www.old.com;
#charset koi8-r;
access_log /var/log/nginx/www.old.com-access.log main;
location ~* ^/abc/123.html { #匹配某一个特定的网页
rewrite (.+) http://www.old.com permanent; #跳转到首页
}
location / {
root /usr/share/nginx/html;
index index.html index.htm;
}
[root@localhost named]# systemctl restart nginx #重启Nginx服务
[root@localhost named]#
